On Monday ISIS supporters humiliated the US military command after they hacked their Twitter and YouTube accounts. This act of "cyber vandalism" saw the hackers infiltrate US Central Command (CENTCOM)—who look after US security interests—social media accounts and change their Twitter profile picture to a masked individual with the words "CyberCaliphate" and "I Love You ISIS."

It's particularly embarrassing because it came on a day when Obama announced new cyber security plans (above), which would mean companies need to inform customers within 30 days if their data has been hacked.

The hack on CENTCOM's Twitter saw the ISIS sympathisers post warnings like "American soldiers, we are coming, watch your back," and "In the name of Allah, the Most Gracious, the Most Merciful, the CyberCaliphate continues its CyberJihad," as well as posting internal military documents.

On CENTCOM's YouTube page the hackers posted two videos called Flames of War ISIS Video and O Soldiers of Truth Go Forth (since removed).

The Pentagon was quick to play down the attack, which caused the account to be suspended for a few hours. Pentagon spokesman Army Colonel Steve Warren said, "It's inconvenient, it's an annoyance but in no way is any sensitive or classified information compromised."

While Defense officials said that "operational military networks were not compromised and there was no operational impact." according to Reuters.
